Communication Port Requirements

To perform their full range of management functions, WDM software components require certain ports to remain open on your servers, routers, and switches.

For example, WDM relies on the HTTP/HTTPS communications port designated by your Web service (such as Microsoft Internet Information Service) for push operations (push refers to operations initiated by WDM and sent/pushed to devices). Push operations include:

•Issuing quick device commands (such as Refresh Device Information, Reboot, Change Device or Network Information, Get Device Configuration, and so on)

•Distributing packages at a specific time (either immediately or at a specific date and time)

Typically, port 80 is designated as the HTTP port and port 443 is designated as the HTTPS port. However, if port 80 (or the designated HTTP port), or port 443 (or the designated HTTPS port) is closed, WDM will be unable to push updates or quick commands to devices.

Table 4 lists the ports WDM uses and describes the respective communication protocols and their function (ensure that these ports are open for proper communication between servers).
